Details:
Decided to set up despite the draining effects of a 35ยบ C day.
C9.25 telescope, x0.63 R/F, Canon 7D Mk II. Tak Mewlon 180 F12 telescope, Tak x1.6 Extender, ASI 174MM ccd camera. Both mounted side-by-side on a Tak EM200 Mount.
The hi-res shot is a composite of the Raw ISS Frames and an aligned/stacked Moon background as processed in Autostakkert!2, using Layer Masks in CS6. This is why the single frame ISS images look rough, whereas the Moon BG looks smoother.
The transit lasted some 0.49 seconds so it was a bit tricky choosing the optimum moment to trip the 7D Mk II which can shoot at 10 fps, whilst remembering to start recording with the ASI 174MM all whilst eye balling the ISS through the C9.25 finder scope. Not to mention fighting off the mossies.
Cheers
Dennis
